It’s hard to overstate the immensity of a $100 billion fortune.

On Friday, Amazon CEO Jeff Bezos, who is already the richest person in the world, became the first person ever to achieve a 12-figure net worth.

In addition to founding the online retail behemoth, Bezos owns The Washington Post and an aerospace company, Blue Origin.

Bezos graduated from Princeton University in 1986 with a degrees in electrical engineering and computer science. As of March 2017, Princeton’s endowment was $22.8 billion, less than one-forth the amount of Bezos current net worth.

Although, he has returned some of his good fortune to the Ivy League. In 2011, Bezos and his wife, also a Princeton grad, donated $15 million to the university to establish a center in the Princeton Neuroscience Institute.

In 1998, Bezos purchased a 5.5-acre waterfront estate in Medina, Washington, a suburb of Seattle, for $10 million. His net worth at the time – one year after Amazon went public – was $1.6 billion, landing him on Forbes’ annual list of the richest people in the world for the first time. The mansion was worth just 0.625% of his total fortune.

Since then, Bezos and his wife have acquired several properties surrounding their estate, creating a compound spanning more than 10 acres. Current estimates value the home at $70 million.

He’s building the biggest home in Washington, DC (aside from The White House).

Bezos became a billionaire in 1998, when Amazon went public. At the time, Buffett was the second richest person in the US, with a net worth of nearly $30 billion.

Nearly 20 years later, Bezos is about $20 billion richer than Buffett.

He may be ‘the first 12-digit man,’ but his net worth could go even higher.
